PROBLEM TO BE SOLVED: To provide a laser module wherein high precision, low cost, and miniaturization can be realized. SOLUTION: The laser module includes a substrate 1, a first laser element 2 placed on the substrate 1, a second laser element 3 placed with an output surface opposed to the first laser element 2 on the substrate 1, and a mirror 7 placed between the first laser element 2 and the second laser element 3. The mirror 7 has a reflective surface capable of reflecting output light from the first laser element 2 or the second laser element 3 in a predetermined direction, and is placed so as to move or rotate between a first position capable of reflecting the output light from the first laser element 2 and a second position capable of reflecting the output light from the second laser element 3.
